Patented June 1l, 1946 ATTACHMENT FITTING John N. Gladden and Leon Zielinski,
Glendale, Calif.
Application December 26, 1942, Serial No. 470,288
Our invention relates to fastening devices, with special reference to fittings for connection to sheets 0r plates, For the purpose of the present disclosure we elect to describe the invention as embodied in a ttingfor releasably connecting inspection plates and other objects to the skin of an airplane. It will be obvious that the invention may have other embodiments for other purposes.
Since the sheet material comprising the skin of an airplane is relatively thin and since an object, such as an inspection plate, must be detachable, it is common practice to mountr on the skin sheet suitable flttings having threads engageable by screws or other attachment means. The imanufacture of such fittings commonly involves severalI machinevoperations and in the aggregate consumes considerable metal.
It .is desirable, especially so in Wartime, to reduce both the manufacturing. cost of the fittings and theamount of metal required. One object of our invention is to providev an attachment fittingpof this type that may be manufactured inexpensively with minimum operations requiring` machine tools. Another object is to provide a tting construction that lends itself readily to the substitution of non-metallic material for metal in a substantial portion of the fitting, and is light in weight.
An attachment fitting of the present type has a base surface for contact with the skin sheet of the airplane. Since the fitting is usually made of relatively rigid material and since the skin sheet of the airplane is relatively flexible, the skin sheet tends to conform to the surface configuration of the fitting base. Since the base Vsurface is flat, and more often than not the skin sheet of an airplane hasl a normal curved configuration, mounting of the fitting usually causes undesirable local distortion and undesirable local stress in the skin sheet. A further object of our invention is to provide a flexible or deformable fitting so that the base surface of the tting may be readily formed to the normal configuration of the skin sheet, thereby to avoid unnecessary local stress in the skin sheet.
Since the skin of an airplane is subject to vibration, it is desirable to incorporate in such a fitting construction some expedient to resist loosening of the associatedscrew means. It is a further object of our invention, therefore, to provide such an vexpedient in a` simple and inexpensive manner.
Our invention'is characterized by the concept of using separate materials for the base portion 19 Claims. (Cl. 85-32) and the screw-engaging portion of the attachment fitting whereby materials best suited for the respective functions of the two portions may be used. A number of objectsof our invention screw-engaging portion and non-metallic material of different properties for the base portion; to provide a construction in which the screwengaging portion is mounted in the material of the base portion, the latter being a base member and the former being an insert embedded in the base member; to provide for embedding such an insert in a manner t0 prevent either relative rotation or 'relative axial movement of the insert; to provide a construction in which the screw loads are transmitted directly to the insert with little or no stress imposed on the base member;- to provide such a dual-part construction in which the base member is made of pliable or deformable non-metallic material to readily conform to any particular skin sheet, even a skin sheet curved in more than one direction; to provide such a construction in which the materialv ofthe base member coacts with the screw means'to resist ll'oosenin of 'the screw means; land to provide such a construction in `vwhich the deformability of the base material is such as to serve a dual purpose, first, in permitting the base member to be flexed to the particular local curvature of a skin sheet, and, second,r in permitting displacement or penetrationlof, the material of the base member by threaded means, thereby to provide vsuch intimate contact with the threaded means as to resist loosening under vibration. v
The above and further objects and advantages of our invention will be apparent in the following detailed description, taken with the accompanying drawing.
In the drawing, which is to be considered as illustrative only:
Fig,'1 is a plan view of a preferred form of our nttins;
Fig. 2 is a bottom view of thetting;
Fig. 3 is a sectional view of the fitting taken as indicated by the line 3-3 of Fig. 2; and
Fig. 4 is asimilar sectional View of the iitting as employed to attach an object'to a skin sheet. The ttingshown in the ldrawing comprises an insert' I0 embedded in aj base member genlera'lly designated Il which as shown constitutes a housing'for the insert I0, The insert I0 is made material of the base member I I in such manner` as to prevent relative rotation of thebase member. formed with a broken peripheralgsurfaogeorpositive engagement by the surrounding material f of the base member to preventrelative rotation.
Thus, in the present construction the'insertilis serrated to provide numerous longitudinal .arecesses I3 forming numerous longitudinal shoulders l5 f orengagementvvith the surrounding material. I ti s als o desirableto provide means for interlo,ck ing thejinsent I Uand the base member I I in a mannerto prevent relative axial movement of thelinsert. 'Ihusin'thepresent construction the linsert IUhas an annular groove I5 forming two j shoulders I'I for positive engagement withthe surrounding material'of the base rmember to prevent rolativeaxial movement o f the in sert. v'For thesamepurpose the bas e mem ber I.I may have ,a flalgeportion I8 overlapping an end surface 1 of` the insertto prevent axial vmovement of the insert relative tothe basemember in ajdireotion away `from the skin sheet 'when the tting is mounted Aona skin sheet, as shown in-Fss. 3 and 4. It .Willjbe noted that the material ofthe base niernberl'l forms'jtheahmllar flange I3 which engagesthe end of theinsert 'I llin apositive manner to prevent y'such relative axialmovement. The base member II has a'housing portionZD embracing .and embeddingthe'insert Ill and has at j least one laterally extendingfportion integral therewithadaptedfor attachment to a skin sheet. :In the present construction Athere are two such lateral portions in the form of wings .2I, the two wingshavingsuitable bores22 to facilitate mount- `Yfi-neraably the nefprmapriity or ,flexibility of 4thematerial ofthe base member IIis such as'to permit'the wing portions 2I to be curved in whatever manner may be required lto conform with the configuration of vthe skinr sheet. AWe have found that Vsome materials ofsuchproperties, for exam- -pleethyl cellulose and Acellulose acetate, may be depended uponadditionally. to cooperate withV the Vscrew means in a novelgmannerjthe screw -means serving as a toolto form threads in the material of the base'member. In'this regard note that in Fig, Sthe annular 'flange I;8 N ofthe base member Adefinesaplain aperture 23 at'the remote or outlet end of .the threaded "bore 25 of the"ins'ert,'the aperture-being ,of a diameter Ysmallerv'than the maximum diameter of the thread-,26 inthe bore and likewise smaller vin diameter than theoutside V`diameter of-'thethread 27 on the screw-:28 shown in Fig. 4.
Eig. 4 1shows .the fitting .mouht ed ontheinner side ofa skin sheet vof an airplanathe fitting being secured by ,suitable rivets 3 'I that pass through .corresponding attachment holes 32 in vvtheskin .sheet. The threaded .bore 2.5! of the-yin'- sert Ill hasy `anentrance endwvhich registerswith Han;attachment vr'opening' 33 in the .-skin @sheet 30 endasubstaoiiellvcooxalaettaohmentoeoniogf 4. in an inspection plate 36. When the screw 28 is inserted in the insert II! and tightened down to the final position shown in Fig. 4, it is apparent that the screw serves as a tool to out a thread in the cylindrical wall of the aperture 23 l formed by the flange I8 of the base member II. The additional thread formed by the screw in the aperture 23 in the base member II cooperates y'with the thread ofltheinsertfn e115 to resist .axial retractionsof thesrew` 2,'=;fandsthe additional thread in the aperture also makes such .intimate frictional contact with the screw as to resist `rotational retraction of the screw under For this purpose rthe insert I') maybev insert in any suitable manner.
vibration.
fItwill-beynoted in Fig. 4 that the tightening of fthe screw 28 draws the insert I0 into pressural contact with the inner surface of the skin i' sheet'sothat loads imposed on theV screw are transmitted directly to the skin sheet without necessarily being transmitted to or through the materialof the base member II. ItWilL be further notedinfFig. 4 that therskin sheet 301s .curved in the planejde'ned by the axeslof v the tworivets 3l and that the fitting corresponds to this curvature. like'rnanner the fitting will `conform toany lateral curvaturein a perpendicular plane definedby lthe axiso'f the. screw'28.
